ST19NR66 3/5 hardware description the device, member of the st19n platform, is a serial access microcontroller specially designed for cost-effective secure portable applications. it is manufactured using an advanced highly reliable st cmos eeprom technology. it is based on the stmicroelectronics 8-bit cpu already implemented on the st19x device family and includes on-chip memories: user rom, user ram and eeprom with state-of- the-art security features. rom, ram and eeprom memories can be configured into partitions with custom ized access rules. an additional st rom contains all st provided functions and libraries. access from any memory area to another are protected by hardware firewalls. access rules are user-defined and can be selected by mask options or during the life of the device. the device includes an enhanced des accelerator which is accessible via cryptographic software libraries located in st rom. the device includes a modular arithmetic pr ocessor (map) based on a 1088-bit processor architecture. it processes modular multiplication, squaring and additional operand calculations up to 2176 bits. the internal map and enhanced des accelerator are designed to speed up cryptographic calculations using public key algorithms and secret key algorithms. an rf interface including an rf universal a synchronous receiver transmitter (rf uart) enables contactless communication up to 848 kbits/s compatible with the iso 14443-b standard. as with the other st19n devices, a serial i/o interface compatible with the iso 7816 standard is available as well as an iso-compatible high-speed iso asynchronous receiver transmitter (iart) enabling communications up to 1.25 mbit/s. a crc calculation block is also available and is directly accessible by the user. 4 .com u datasheet
